A JSONObject text must begin with '{' error

Question

I have this JSON coming from one of our REST service:

[
    \"{\\\"category_name\\\":[\\\"Industry Components\\\"],\\\"categoryId\\\":[1]}\",
    \"{\\\"category         


        

Answer 1

I suppose that you should use not JSONObject, but JSONArray

Answer 2

JSON Object follows the following Structure:

{
 "array": [
{
    color: "red",
    value: "#f00"
},
{
    color: "green",
    value: "#0f0"
}
]
}

JSON Array follows the following Structure:

[
 { "firstName":"John" , "lastName":"Doe" }, 
 { "firstName":"Anna" , "lastName":"Smith" }, 
 { "firstName":"Peter" , "lastName": "Jones" }
]

Answer 3

instead

JSONObject jsonObject = new JSONObject(jsonStr);

use

JSONArray jsonArray = new JSONArray(jsonStr);

and may be read about Gson is a nice library for parsing and work with json

Answer 4

If you get JSONObject text must begin with '{' exception. Then first off all check what did u pass to the JSONObject constructor.

You should pass the right json.txt file.So make sure what are u passing to jsonobject.

String request = FileUtils.readFileToString(new File("/home/achaure/Downloads/Amol/KountRestTest/Documents/request.txt"));

JSONObject jsonObject = new JSONObject(request);
